morphological structure

The domain of morphology is words. How words are formed is the concern of this field so morphological structure is the structure which consists of the elements to form words. The most common word formation in language including English is affixation. Affixation is the process of word formation by adding the affixes or bound morphemes in bases or roots (free morphemes). In other words morphological structure is the structure or forms of words primarily through the use of morpheme construct (Crystal, 1980: 232).
Morpheme is defined as the smallest meaningful unit of language (Lim Kiat Boey, 1975 : 37). Morphemes can be divided into two namely free morphemes and bound morphemes. Morphemes are the components which build words. The word singers, for example, consists of three meaningful units or morphemes, sing, –er, and –s. The morpheme sing which forms the word singers has the lexical meaning; the morpheme –er means the doer of singing; the morpheme –s has plural meaning. We can identify the meaning of the morpheme sing although it stands alone but we cannot identify the meaning of morphemes –er and –s in isolation. We can identify the meaning of the morpheme –er and –s after they combine to the morpheme sing. Sing which can meaningfully stand alone is called free morpheme while the morphemes such as –er and –s, which cannot meaningfully stand alone are called bound morphemes. Bound morphemes must be attached to free morphemes. Bound morphemes are also called affixes which can be classified into prefix, infix, and suffix. English only has two kinds of bound morphemes namely prefixes and suffixes. No infixes exist in English. Bound morphemes are classified into two types namely derivational and inflectional morphemes. Both inflectional and derivational morphemes play an important role in the larger structure namely syntactic structure.

morphology

In linguistics, morphology is the identification, analysis and description of the structure of morphemes and other units of meaning in a language like words, affixes, and parts of speech and intonation/stress, implied context (words in a lexicon are the subject matter of lexicology). Morphological typology represents a way of classifying languages according to the ways by which morphemes are used in a language —from the analytic that use only isolated morphemes, through the agglutinative ("stuck-together") and fusional languages that use bound morphemes (affixes), up to the polysynthetic, which compress lots of separate morphemes into single words.

While words are generally accepted as being (with clitics) the smallest units of syntax, it is clear that in most languages, if not all, words can be related to other words by rules (grammars). For example, English speakers recognize that the words dog and dogs are closely related — differentiated only by the plurality morpheme "-s," which is only found bound to nouns, and is never separate. Speakers of English (a fusional language) recognize these relations from their tacit knowledge of the rules of word formation in English. They infer intuitively that dog is to dogs as cat is to cats; similarly, dog is to dog catcher as dish is to dishwasher, in one sense. The rules understood by the speaker reflect specific patterns, or regularities, in the way words are formed from smaller units and how those smaller units interact in speech. In this way, morphology is the branch of linguistics that studies patterns of word formation within and across languages, and attempts to formulate rules that model the knowledge of the speakers of those languages.

A language like Classical Chinese instead uses unbound ("free") morphemes, but depends on post-phrase affixes, and word order to convey meaning. However, this cannot be said of present-day Mandarin, in which most words are compounds (around 80%), and most roots are bound.

In the Chinese languages, these are understood as grammars that represent the morphology of the language. Beyond the agglutinative languages, a polysynthetic language like Chukchi will have words composed of many morphemes: The word "təmeyŋəlevtpəγtərkən" is composed of eight morphemes t-ə-meyŋ-ə-levt-pəγt-ə-rkən, that can be glossed 1.SG.SUBJ-great-head-hurt-PRES.1, meaning 'I have a fierce headache.' The morphology of such languages allow for each consonant and vowel to be understood as morphemes, just as the grammars of the language key the usage and understanding of each morpheme.
